Naturepedic 2-in-1 Organic Kids Mattress - Twin Trundle Mattress with Quilted Top and Waterproof Layer - Firm for Kids

This is not a 6” mattress. It’s 3” and absolutely smells. Mine has stains on it. The return process is brutal. Buy from elsewhere

My preschooler was having chronic allergies/asthma attacks every night until I realized his toxic mattress was the culprit. I wish I bought an organic mattress years ago! The first night he laid his head down on this mattress, he didn't cough a single time. I wasn't paid to write this review ya'll. If you're a parent of a toddler/bed wetter the waterproof side makes PM potty training less daunting. BUY THE MATTRESS. Also want to mention, I've fallen asleep next to him on the new mattress & I've never slept deeper. Although it's firm, it's much better for my neck & back issues -- I've since purchased a 2nd mattress from Naturepedic. I'm thrilled & Ill tell everyone about this wonderful, AMERICAN company, THANK YOU!!!

Materials are quality and it fits nicely in a twin bunk. Best of all it had no off gassing or smell at all. It's not as soft as I would like but my kids have not complained.
